JG...Since you have a background in geology maybe you can help me out. I cant us limestone on the pond water fall because it will make the water too alkaline. If I post a pic of what I have on there now, can you try to ID it for me?

Use a few drops of vinegar on the rock in a few different places. Works the same as aragonite. Except this time if it fizz's, you can't use it.

This will work, but if the stone has been exposed to weather, a glaze or varnish will form that will prevent the vinegar from reacting. A fresh surface works best so either break a small chunk off or scratch the surface until a small pile of rock dust forms. Then use the acid.

Limestone also smells "musty" if you take a dry piece breathe on it then sniff. ( Imagine a large group of geology student out in the field sniffing rocks)

The sharp edges break off pretty easily, so ill just get a fresh edge and pour a little on that. Thanks for the tip.

And as for the "J/C" reference. I saw it a lot like the story that Bill Cosby used to tell. He said that growing up he and his brother though their names were D*mn It and Jesus Christ. He said one day it started raining and he stayed out in the yard playing. A few minutes later his dad sticks his head out the front door and yells "D*mn It, get in here." He turns around and yells back "But Dad, I'm Jesus Christ!"

It was meant to be humorous. No one hits their finger with a hammer and yells "Lucifer." So...it just wouldnt have been as funny. Not to mention, I just told it like it happened. I didnt mean to offend anyone.

as for the story, hilarious, i just hope you can use the rock after all of that, keep us posted.

p.s i didn't mind the cursing, i agree that it added humor to your story. if people are offended then its their problem, they can always just stop reading the post, and move on. so don't worry about it!
